How to Clean Oil From Under Car? You can clean oil from under car by turning off the engine, raising both ends of the automobile, and soaking excess oil from all components with the help of a towel. Brush off the dirt with a tiny brush and rinse with warm water. Apply a degreaser or a detergent solution to remove oil, then let it dry and apply a protectant to all the parts.

Cleaning the under of the vehicle is time taking and nasty process. You have to make a lot of preparation before cleaning the fuel residue from underneath the car. It can take up to 1 hour to completely clean the surface.

Why is oil present under the car?

Oil serves as a fuel to produce the power in the combustion engine. It runs through the different compartments of the engine and other systems to produce energy and lubricate the components.

Sometimes grease serves to lubricate all the parts to run the vehicle. But oil and grease can stick to different parts.

The presence of a thin layer of oil is not worrisome. However, oil and grease leakage can make a thin film around all the structures. 

But heavy leakage indicates severe damage to the engine and other components. 

The leakage from the engine is due to a fault in the seals f the valve. The holes or corrosion in the oil pan can cause the oil to leak from the fuel system. Worn out engine gasket is also responsible for oil leakage.

Methods to clean oil from under car

Cleaning the thin layer of fuel is essential to maintain the healthy condition and function of the engine and other parts.

It is a simple procedure, and you can do it alone. Just gather the right tools and materials to start the process.

Turn off the engine

You should turn off the engine before starting the procedure. The engine in working condition is too hot to touch. Avoid touching and cleaning a hot vehicle. Let the engine cool for some time.

Park the vehicle in an open area in an illuminated area and unplug all the cables of all electronic appliances.

You can use a plastic bag to cover all the cables to prevent them from any damage. You can also remove the cables of the battery to turn off the electricity supply. Then cover all the electronics in the car to protect them from water and other liquid.

Raise both ends of the car

It is essential to raise the vehicle from the front and rear sides to clean it from the underside. It will increase the ground clearance of the automobile.

You can lay beneath the frame and have a complete look at the vehicle. It is also helpful in finding the source of oil leakage.

You can use a jack stand to raise both ends with the help of a friend. First, find the jack spot on both sides of the vehicle. Then choose a compatible jack stand to place on both sides.

Then adjust the stand height to raise the front and rear ends to a suitable height. Finally, choose a metallic jack stand, as metallic stands can withstand the pressure of a heavy vehicle.

Soak excess oil

Inspect all the parts of the car and find out the leakage source. First, seal the leakage point with glue or other sealants.

Heavy leakage can cause oil spillage on the ground. It will also make a thick layer of oil in the engine compartment.

Before cleaning the stubborn grease and oil, soak all the excess oil present on the ground. You can use old towels or paper towels to soak the fuel. Cotton towels are excellent in absorbing all extra fuel.

Rub it gently on all the parts to absorb the oil. I often use a vacuum cleaner to suck up oil on the ground. The vacuum cleaner with a hose attachment can suck all the liquids within minutes.

Brush off all debris

The dirt and debris can easily stick to an oily place. They mix up with oil and make a dirty layer around the pipes and other components.

Wear safety gloves before touching such pipes. It can contaminate your hands and dress. Also, it is difficult to dust off dirt and debris.

You can use a tiny brush to brush off the dirt. Brush having hard bristles are suitable for this purpose. You can moisten the bristles before rubbing them on the targeted site.

You can use a blast washer to remove debris under the vehicle. It can easily wipe away all the dirt from the nook and corners.

Apply degreaser

A thick layer of oil and dirt can make a thick cake layer under the vehicle. It is difficult to remove the caked layer with a brush or towel. In such a situation, use a degreaser to get rid of the nasty layer.

Choose a good quality degreaser to remove the grease and tar from the engine components. For example, WD-40 is an excellent degreaser for removing oil from the car’s underside.

Spray it on all the engine parts and other components to clean the surfaces. Let the degreaser stay there for at least 30 minutes.

It will lubricate the dry layer of grease. In addition, it will make the grease lose its grip on the engine compartments.

Then you can use a scrubber to remove the grease. Gently rub it on all sides and remove the grease and tar.

Then you can use water to rinse the surface. It will help clean all parts on the underside. Then use a dry cloth to soak excess water from all the components.

Rinse with warm water

Warm water helps melt the dried-out oil layer; it is an effective and cheap option for cleaning the oil. You need warm water to cleanse the oil and dirt.

You can directly sprinkle warm water under the automobile through a washer. But be careful not to wet the cables of the battery and other electronics.

For minor stains and dirt, use a damp cloth to clean the engine and other components. You can soak a clean cloth in warm water. Then rub it on all the sides where oil stains are present.

It will take some time and effort. You may have to repeat the procedure to remove the fuel stains from the car.

Use soap solution

Use a soapy solution to clean the oil stains from under the vehicle. It is also an affordable option to clean any surface.

You will need a strong detergent and water to make a solution. Pour some detergent into a bucket and add water to it.

Mix them vigorously until a soapy solution is formed. Next, you can spray the solution on all the parts of the car. You can also use a sponge to cleanse the stubborn oil stains.

Then apply the detergent solution to the oil stains and rub it with a sponge. When the stain is removed, use a paper towel or clean cloth to remove the solution.

Finally, you can use Luke warm water to clean up the detergent solution from the vehicle’s underside.

Apply protectant

Applying a protectant is essential for proper maintenance of all parts of the car. It helps in the accumulation of dirt and filth on the surfaces of all components.

It also helps in protecting surfaces from rust and corrosion. In addition, it prevents the formation of a caked oil layer underneath the vehicle. As a result, the grease and tar cannot stick to the engine compartments.

Choose a high-quality protectant and apply it all around the underside of the vehicle. Spray bottles are suitable for evenly spreading the protectant on all sides. Then let the protectant dry in the open air.

How often to clean the oil from under the car?

The under of the vehicle is exposed to all kinds of dirt and pollution. In addition, oil leakage from the oil pan also creates a layer of oil on the underside of a vehicle.

To prevent the build-up of filthy layers, cleaning the oil 3 to 4 times a year is advisable.

Proper cleaning can prolong the life of the engine and other components. Also, regularly inspect the underside to notice the parts’ condition.
